Definitions

  • the present invention relates to petroleum-based fuels, and in particular, relates to a light-fraction based fuel composition for compression ignited engines.
  • Embodiments of the present invention provide a light fraction fuel composition for compression-ignited engines that comprises about 25 v/v% to about 50 v/v% commercial diesel fuel; about 40 v/v% to about 69 v/v% straight run heavy naphtha about 5 v/v% to about 10 v/v% n-butanol; and about 0.2 v/v% to about 1.7 v/v% 2-Ethylhexyl nitrate.
  • the relative percentages of commercial diesel fuel and straight run heavy naphtha are controlled to obtain a cetane number of at least 51 for a selected engine, and the relative percentages of commercial diesel fuel and straight run heavy naphtha are controlled to obtain a Reid vapor pressure in a range of about 7.28 PSI and about 10.88 PSI for a selected engine.
  • the relative percentages of commercial diesel fuel and straight run heavy naphtha are controlled to obtain a boiling point range of about 30C (initial) to about 350C (final).
  • the light fraction fuel composition includes about 26 v/v% commercial diesel, about 68 v/v% straight run heavy naphtha, about 5 v/v% n-butanol and about 1.0 % 2-Ethylhexyl nitrate.
  • the light fraction fuel composition includes about 45 v/v% commercial diesel, about 49 v/v% straight run heavy naphtha, about 5 v/v% n-butanol and about 1.0 % 2-Ethylhexyl nitrate.
  • the light fraction fuel composition for compression-ignited engines comprises about 0 v/v% to about 50 v/v% commercial diesel fuel; about 40 v/v% to about 95 v/v% straight run heavy naphtha about 5 v/v% to about 10 v/v% n-butanol; and about 0.2 v/v% to about 1.7 v/v% 2-Ethylhexyl nitrate.
  • FIG. 1 is a graph showing a relationship between viscosity and the percentage of light fraction in the fuel composition.
  • FIG. 2 is a graph showing the evaporated volume fraction by distillation temperature for the three fuel variants.
  • Embodiments of the present invention provide a fuel composition for compression ignition engines that includes about 40 volume percent (v/v%) to about 94 v/v% straight run heavy naphtha (referred to as the “light fraction”), about 0 v/v% to about 50 v/v% commercial diesel fuel, about 5 v/v% to about 10 v/v% n-butanol, and about 0.2 v/v% to about 1.7 v/v% 2-EHN (2-ethylhexyl nitrate). Fuel variants having different blends within these ranges were tested on conventional Cl engines. Through these tests it has been determined that blends of light fraction with commercial diesel can be used as drop-in replacements for commercial diesel that yield reduced carbon dioxide and soot emissions.
  • straight run naphtha has higher LHV (lower heating value) and a higher hydrogen to carbon ratio (H/C) than commercial diesel fuel
  • H/C hydrogen to carbon ratio
  • straight run naphtha has a lower polyaromatic hydrocarbon content than commercial diesel fuel.
  • polyaromatic hydrocarbons are often soot (smoke) precursors, by reducing their content, it is possible to decrease the smoke out of the engine without altering emissions of NOx, HC and CO.
  • testing has shown that variants of the novel fuel met targeted specifications without sacrificing any of the desired properties required for a drop-in fuel for compression-ignition engines.
  • the light fraction fuel composition of the present invention provides economic benefits in terms of improved refinery margins.
  • FIG. 1 is a graph showing a relationship between viscosity and the percentage of light fraction in the fuel composition.
  • FIG. 1 is a graph showing the evaporated volume fraction by distillation temperature for the three variants.
  • This graph shows that the greater fraction of diesel present, the greater fraction remains unevaporated over the 50 to 300 °C span. For example, at 200 °C, approximately 50 percent of GD50 (variant with the highest diesel percentage) evaporates, whereas, at the same temperature, all of the GD100 evaporates, and approximately 80 percent of GD75 evaporates. This can be explained by the fact that the lighter straight-run naphtha component evaporates at lower temperatures than the heavier diesel component. Table I lists the main properties of the three tested fuel variants.
  • Table II lists the minimal and maximal values (range) of properties across the three tested fuel variants. Any final blend formulation within the ranges set forth below will be engine-specific and depend on the experimental performance and durability of the fuel injection system of the specific engine type.
  • Table III lists experimental emission results of tests performed on the Volvo MD11 compression ignition engine in terms of relative variation from a 100% diesel baseline.
  • the Volvo tests included both drop-in replacement tests, and tests performed using optimized injection settings in order to understand the potential of the fuel variants.
  • a notable feature of the results of the Volvo engine tests is that when light fraction is blended with commercial diesel as a drop-in replacement without optimization, NO x emissions decrease but soot emissions increase and efficiency slightly decreases for all variants. However, when injection settings are optimized, NOx emissions are largely unchanged, while soot emissions markedly decrease and efficiency marginally increases, particularly for GD75 and GD100. These results show that soot emissions can be reduced at approximately constant NO x and efficiency.
  • Table IV lists experimental emission results of tests performed om the Cummins ISX 15 compression ignition engine, in this case listing both absolute values and relative variation from a 100% diesel baseline.
  • the test results on the Cummins engine with the higher light fraction percentage-fuels (GD100, GD75) indicate that C02 emissions decrease 3.25-4.25%, and soot decreases more markedly between 27-45%, at approximately constant NOx and efficiency. Accordingly, the fuel composition of the present invention can be seen as a significant improvement over commercial diesel in terms of emission reduction.
  • Fuel variants according to the present invention can provide global and local pollutant reduction without requiring software modifications while leveraging existing diesel engine hardware. It is believed that in certain implementations, adjustments can be made to certain diesel equipment to better accommodate the novel formulation. For example, the caps of diesel tanks can be modified to be airtight, and additional mechanisms can be employed to balance the pressure inside the tank.
